This is an idea I wish I'd have come up with. It's a jar full of organic menthol crystals capped with a grinder that turns the menthol crystals into menthol salt so it'll incorporate easier and disolve quicker. (A pepper grinder). It allows you to turn any of your soaps into a mentholated soap. Two great advantages: you choose a soap and based on the amount of menthol you add gives you the option of just a kiss of menthol or by adding more, bobbing for apples in liquid nitrogen face freezing menthol. And the second benefit is after a rinse the soap is no more mentholated than it was before you used the crystals. The way I use it is by wetting the top of the soap and grinding some menthol on it before getting in the shower. By the time I exit, the menthol is dissolved and I load my brush and face lather. The cold builds from pass to pass and the effect lasts about an hour. So if you ever wondered what a cold Tabac was like, poof, you got mentholated Tabac. Brilliant idea to turn a pepper grinder into a shaving tool.

Lather

Well, it's not a soap so lather will be what soap you choose.

Skin Feel

Menthol mild or wild

Slickness

Again, it's a soap amendment so you choose the slickness.

Scent

It does affect the scent of your chosen soap. Menthol minty. Wish it was neutral but no way around it.
